Buying a used car from a dealer. Questions and shit

Is there a grace period for insurance or anything like that? I'm planning on buying a car in socal then driving it up to San Francisco. The car prices are at least 2-3 thousand cheaper for some reason (same car same mileage)

I think it depends on your insurance company.Some do, some don't, call them to find out for sure.With technology today, really no excuse to be driving off the lot uninsured lol.

It's a bit harder to haggle the price of a sports car than lets say compared to a camry.Most dealerships have no problem selling sport cars. G35s especially. There will always be someone who wants to buy it, sometimes for even more than what it's worth.My suggestion though, find as many flaws as you can in the car and point them out. Then haggle.Try not to show any interest in the car either, just pretend like you were just browsing and checking stuff out.
